SPECIFICATION forming part of Letters Patent No. 465,902, dated December 29, 1891. Application filed October 7, 1891. Serial No. 408,014. (No model.)

To all whom it may concern.-

Be it known that I, CHRISTOPHER BUS WVARREN, a citizen of the United States, residing at Siding, in the county of Lauderdale and State of Mississippi, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivators, and the objects in view are to provide a cultivator of cheap and simple construction, which is readily manufactured, will be strong and durable, and which may be changed so as to perform the different offices of a cultivator, or, in other words, adapted for various kinds of cultivation.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a cultivator constructed in accordance with my invention. Fig. 2 is a detail, in perspective, of the central standard. Fig. 3 is a similar view of one of the side standards.

Like numerals of reference indicate like parts in all the figures of the drawings.-

1 designates the beam, which may be formed of iron or wood, and is provided at its rear end with the usual handles 2, diverging toward their rear ends and connected by the rung, as is usual. Three standards, designated as the central standard 3 and side standards 4, are employed, and each is constructed of a single piece of flat bar-iron of suitable thickness and in a manner that will be hereinafter obvious.

In constructing the central standard a blank of bar-iron of suitable length is bent upon itself to form the standard portion 5, and the two terminals at a suitable point are doubled or lapped upon themselves, as at 6, to form securing-plates 7, which are applied to the opposite sidesof the beam and are disposed at an acute angle to the standard.

In forming the side standards a blank of suitable length is bent at its center, so as to form the standard portions 8, and the two terminals are bent upon themselves, as at 9, and bolted to the opposite sides of spaceblocks 10 by means of bolts 12. These termi nals after being bent and bolted, as described,

are given a disposition to form a substantial right-angled triangle, the inner terminal being inwardly bent, then forwardly bent to form a securing-plate 13, and the outer terminal being simply diagonally disposed. The beam 1 and the securing-plates of the central standard are at intervals provided with boltopenings, and by means of bolts 15, passed through the securing-plates of the side standards and the extremities of said plates and the diagonal braces thereof, said side stand ards may be adjusted along the beam both with relation to each other and also with relation to the central standard.

Each of the standards, it will be observed, has its terminals spaced apart either by the beam or the space-blocks, as indicated at 16, and at its lower front edges is provided with a series of inclined notches 17. These notches receive in an adjustable manner the three shovels 18, and through the shovels and the spaces between the terminals of the standards heel-bolts 19 are passed.

From the foregoing description it will be seen that I have provided a cultivator of great simplicity and strength, as'well as durability. By the adj ustability of the side standards the plows may be thrown either into or out of transverse alignment, or the side plows may be removed entirely and thus the cultivator used for various operations.

Having described my invention, what I claim is-- 1. The combination, with the plow-beam, of the central standard formed of metal and consisting of a blank bent at its center to form the standard, the terminals being rebent upon themselves to form opposite securing-plates and bolted to the beam, and the plow-shovel bolted to the lower end of the standard, substantially as specified.

2. The combination, with the plow-beam having a series of perforations, the central standard formed of a bar of metal bent at its center and having its terminals rebent upon themselves and embracing the opposite sides of the beam, the opposite .side standards formed of bars of metal bent at their centers and having their opposite terminals rebent upon themselves, the inner terminals being inwardly disposed parallel to the beam and the outer terminals inclined to form braces, In testimony that I claim the foregoing as space-blocks located between the bent termimy own I have hereto affixed my signature in nals of the standards, bolts passed therethe presence of two witnesses.
